I had watched Andrew video on tweeter types. In the video he shows few metal dome tweeters. The tweeter he showed in the video looks very small compared to other tweeters from Revel and other brands Dynaudio. https://www.youtube.com/watch?v=AYG98-j8rDA&list=PL1pj9vtyLGBdrlKvfJuDsbAUeTDocvUfj&index=19

I understand that overall design (crossover and cabinet) is important but I was looking only to assess the quality of the parts.

Axiom has information on HP drivers used in M5HP on the website. I was looking for similar information about the tweeter.

Thanks @Hambrabi for sending me the link to the video. I was looking for similar videos made by Axiom but that covers improvements to the tweeters.

I just found this video on titanium tweeters from Andrew. I am going to watch it entirely and see if it provides the information I am looking for.
